Pulitzer Prize winning American author Jennifer Egan has received critical acclaim for her novel A Visit From The Goon Squad.

Reviews gushed about its apparently experimental nature, including a chapter laid out on the pages in the form of a PowerPoint slide presentation.

Speaking to a sold-out audience here at the Edinburgh book festival on Monday evening, Egan said the book was less experimental than reviews had suggested.

Among those in the audience was Canada-born Tim Caulfield, 47, a visiting law professor at the University of Edinburgh.

In the Audioboo clip below he tells us what question he put to the author. He said he was thrilled to discover Egan had based part of her research on one of his favourite books, So You Wanna Be a Rock & Roll Star by Semisonic drummer Jacob Slichter.
